can yhe readily and quickly applied to existing types of vehicles7 which is simple in construction, durable and reliable in use, and inexpensive to manufacture. and advantages Will be apparent from the following description and the novel features oi my invention Will be particularly pointed The invention comprehends the provision of a rod Which is pivotally securedto one Ao the relatively movingparts such as the cross steering rod. a casing which is pivot- 'a'lly secured to the other of the parts such `as the liront axle and into which casing the rod projectsv and locking mechanism which is carriedivithin the casingy and which in one condition locks the casing against pivotal movement on the axle and the rod against removal from the casing1 and in the vother condition unlocks both.v The cover of invention thereto, the .locked position of the 'movable ,parts 'being sho-Wn in lull lines and the normal straight forward running position oit these parts being` indicated the dotted lines.

` 2 is a plan of a loch constructed. in accordance with myv invention. "a portion of the `cover of the 'casing-'having been removed in order to show the locking; mechanism Within'the easing in itsloc'ked condition.

is arplan vsimilarto Fig. but with the -l'f'i'cliin'g7 mechanism in its unlocked con` (dition.

lis a sectional elevation of the locking dei/*ice and the vehicle parts to which it y'is attached.

Fig. 5 is a sectional elevation taken substantially alongl the line 5 5 ,of Fig. 4.

Fig'. 6 is a transverse sectional elevation our' thedevice. the locking mechanism being in locked condition.

Fig. 7 is a sectional elevation somewhat similar to that of Fig. 6 vbut with lthe mechanism in its unlocked condition 'and p Other objects'v Fig. 8 is a plan oit the under tace of the cover oit the casing.

ln the illustrated embodiment I pivotally secure a casingl Ato the front aXle 2 ofa vehicle, and reciprocating' in the casing is one end ot a locking' bar or rod 3 which is pivot-ally secured to the cross connecting or steering rod 4 by means of which the.

steering knuckles of the wheels 6 (only one oit which knuckles and wheels is shown) are caused to` movein unison whenever one or" them is shifted by the rod 6, under the control oit the steering wheel (not shown). The bar 3 is pivoted bya bolt 8 to the dat top of one section 9a of a split collar 9, the other section 9b ot which is secured to the section 9EL by the capv screws 10 which `pass through one section and thread into the other section. The bolt 8 is provided with a round head 11 which is countersunlr into the upper face oi' the bar or rod 3, and with a nut 12 which is disposed within a cavity 13m the under tace of the upper section 9'EL ot the split collar. i

The upper section of the split collar is provided with cavities or depressions 14 which receive therein the heads of the cap screws 10. ,When thebar 3 extends .trans`- versely of the Across steering rodit covers both of these cavities 14 and prevents access being; had to the cap screws 10. In order to obtain access to the cavities 14 and cap screw the bar 2 must loe shifted until it is substantially parallel with the cross steeringrod, the'bar being narrow enough to expose the cavities when in this position. Split bushing elements 15 are gripped be- ,tween the two sections of the collar` and the bushing),l elements `in turn grip the crosls steering rod. Thus when the cap screws v10 are tightened the bushing` elements 15 will be forced together andinto ,gripping engagement with the cross rod. The cross rod passes through the bushing; elements 15 eccentrically thereoil so that it the cap screws 19 are loosened to release the bush ingelements the latter can be rotated about the cross rod and then by tightening' oi. the screw clamp the split collar will be clamped securely to the cross rod.- The rotation of the bushingelements carries therewith the `split collar so that the latter is given a movement upon the cross rod like that of an eccentric strapr and this movement is utilized in adjusting'y this lock for attachment to various makes ot vehicles, as .will be more fully hereinafter described. In order that the bushing elements can not be removed by driving from the split'collar in a direction longitudinally of the cross rod l provide reduced annular end portions 16 upon the bushing elements 15 and provide internal flanged rings 17 ateach end of the split collar which engage over the reduced end portions 16 and lock the bushings y of the casing.

Lef-sence against endwise movement,` relatively to the collar.

VUpon the front axle 2 is placed a U- shaped member 1S with the arms 19 thereofy embracing the sides of the axle. rlhe arms 19 are of a length sufficient to bring their free endssubstantially in line with the upper `tace of the axle and upon the free ends of these arms and passing over the axle is a clamping plate 2O which is secured to the arms 19 by means of cap screws 21 countersunk into the plate 2O by means ot' cavities 22 and threadedy lengthwise into the arms 19. The cavities 22 in the upper face of the plate 2O are larger than the heads oi the cap screws 21 and togetherwith elongated slots 23 in the plate which yconnect the cavities 22 to the lower Jface of the plate and through whichthe cap screws 21 pass, permit of a slight movementof the plate relatively tothe arms 19 and transversely of the axle, and thisl limited adjustment is utilized in adjusting` the lock to various sizes of vehicles. The tightening` ofthe cap screws 21v securely clamps the plate 22 to the U shaped member 1S in the adjusted position. A bearing plate 24 is placed upon the upper face of the plate v2() and a plurality of dowel pins 25 extend ldownwardly therefrom into cavities or recesses 26 of the plate 20`i'n order to prevent movement clamping member 18 and the plate 2O from rthe aXle. The casing 1 is pivotally secured to the plate 2O by means oli a cap screw 2T which passes through the bottom wall of the casing and the bearing plate 24 and is threaded into the *plate 20 the head ot' the screw being' preferably `countersunk in the bottom wall The casing' is substantially cocrrtensive in area with theplates and 2O and when in place thereby preventa` removal of the plate 24 and the plate 2O rljhe bar 3 at one end is reciprocatin 'ly received into the end wall of the casing; nd entends considerably into the interior ot the casing' The abutments 28 and 29 on the interior of the casing1 guide the bar in its reciprocations into and out of the casing; and provide in effect an elongated bearing surface. A..

pin Av30 projects upwardly trom, the bottom l wall of the cc sing beneath the bar 3 and by its engagement with the slot 31 in the under side of the bar alsoassists in `rguiding' thc bar 3 into and out oi the casingr without binding'. The casing is provided with a removable cover 32 which has a loop 33 dejpendinginto the casing through which the bar 3 passes when the latter is inserted into the casing. Thus the cover is locked against removal from the casing as long as the bar vfrom the 'casing by unscrewing.

3: is within the casing'. rllhe over is also provided with a .depending L shaped lug' or half loop 34 which engages under the bar 3 at one side ot the same to torni an additional lock between the cover and the as ing. The interior `ot the casing; is 1 i with a lug having a slot 36 therein eX- tending transversely ot the casing' which receives one end of a bar 3T pivotally secured at 38 to a locking' bolt 39. The locking` bolt 39 is mounted for vertical reciprocation through the bottom Wall oit the lrising and intoand` out of engagement with a locking; cav-ityltO in the bearing plate :24. A. spring' 41 secured at 42 to the lug bears upon the upper'endf ot the locking bolt 39 and tends to shift the same downwardly and into the cavity 40 when the position ol the casing is. such as to bring them into alignment.

A pawl or lever 42 is pivoted by means ot a screw 43 to the bottom ot' the easing and oneend of the paivl or lever is prov.' ded with a cam surface 44 which is adapted to move into engagement with the cam surface upon the end oi the bar 37, and operate the latter to cam the bar 3'? upwardly about the lug 35 als a fulcrum and retract the locking' bolt 39 into the casing` and out ot lockingv engagement with 'the plate 24. 'The opposite end of the paWl or lever 42 is provided with a hool lfwhich engages in an elongated notchil` in one edge ot the bar 3 and prevents" removal' ot the bar 'from the casinv during'4 vsuchl engagement or removal tar enough to re-l'easethe cover. l spring; L8 is disposed between the Wall ot the casing' and the pavvl or lever 42 to normally shift the latter so as to bring the hoolr Il@ into locking engagement With the bar 3 and to shift the cam'surface le out of engagement with the bar 37 and release the locking' bolt 39.

4 vThe Jfront Wall of the casing is proifiderl With an aperture within which is threaded a lock 4:9, `and a pin 50 passes through the casingy Wall and into the lock :from the casing so as to secure it against removal y The pin 50 vis placed in the Wall of the casina' to lie beneath the cover32 and be concealed there by ivhen the latter is in place. 1ill'hile va" typesmfof locks' may be employed. l a lock of the rotary cylinder type wh'. be purchased inthe open market and Thich has therein a rotatable cylinder operable by a key,` the cylinder having upon the end vvhich projects into the casing` a cam member 51 yWhich yiS concentric, with an operating' cam 52 rotatably carried by the inner end ot` the lug'. The operating' cam `52 is pro-y vided with pins 53 which are engaged alternately by the cam member 51 and shrlted thereby. Vhen the cylinder is rotated bv a suitable key the cam member 5l ivill e 'ge with one of the pins 53 and shift the ope ating cam 52 about the z Xis of the cylinder and Yithin rotary cyliu;

into or out ot engagement with that end o' the' paivl 4:2 having the cami surface el thereon. TWhen the operating cam enp fes the pawl, it rotates the same against the action of the spring t3 to sl the locking: hoolr 4:3 out or' engagement ith the notrh lll ot the bar 3 and holds it in dieenw'aged position, so as to permit oi" tree reci ,ication of the bar Within` the casing'. At the same time that the bar 3 disengan'erl the cam surface it of the pavvl will engi' ,gre with 'the cam surface 4l?) ot the bar and cani the latter upwardly to retract the locking bolt 39 into the casing' and unlock the latter for rotation across the plate 24. This permits' the casing to rotate about its pivot 2. When the cylinder is rotated. by the lief.' in the opposite direction the cam member 5l will engage with the other ot the spaced pins 53 and shift the operating' cam 52 out ot engagement with the paivl 4t2 whereupon the spring L8 Will shift the lever' or pawl to .carry the locking tooth It@ thereof into the notch et? oit the bar and lock the latter against removal. trom the casing' or removal far enough to release the cover. The movement of the cam surface 4A ot the paivl from beneath the bar 3T releases the locking; bolt 39 to the action ot' the sr 'ingr Litl. Whereupon the latter thrusts the bolt 39 outwardlyr and against the bearing' plate 9A. fla the casing is rotated about its pivot due to the n 'iovement o'l the bar 3 and cross steering' rod il, the locking' bolt 39 ivi l be Jforced bv the spring Lil into the cavity All) as soon as it is `brought into alignment therewith and thus lock the casing' a st further movement in both directions. the operating cam will be locked in each ot the operative positions mentioned.. when. the hey is reniioved 'from the cylinder. due to its internal con struction which is not per se a part or this invention.

The cams 5l and 52 are secured to the ller in any convenient mani'ier as i' K/t and in order to "r de f ci i of .ie saine :is desired. to a vehicle the oar ie lu; ln applying' this loc.

The tl shaned cV elemeiit l@ is passed inrvvard y iva-rdlv te embrace tl e 'Front axle 2. in ward and rearwa l ali J" r:nment with ine split collar and the plate 2() is placed across the tance between the fron axle and 4: incense ends of the arms of the Ushaipiofl clamping elerientanr ecured thereto by the sere 2l. The be, 'ing plate 241 is placed upon t e olate 9,0 with the dovrel pins inthe recesses ,i6 of the plate. 'l "lien secured to the plates 21; and 2G by p I sing the pivotal securing` screw7 27 throuvh the d plate 2e into the clar cross rod et is next dis from the knuckle of in an aperture in the end of the casin cross r d is then lixrought foraTn e i secured to the lrnuclrle. lf the bar f on the level With the aperture in the end of the casing the clamping screws 1G of thesplit section may be loose Led slightly the bushing elements lo rotated to ate or lower the split collar uimil the is brought into alignment with the aper ire in the end of the casing1 The screivs l() will then be tightened to securely clamp the split collar is not to cross rod and the end of the bar in"` sorted in the end ofthe casing as hereinn before described. ln vehicles Where the disl the cross rod is exceptionally eat or small die plate 20 can be adjusted slightly along` the upper or lower face of the axle ly means of tl e cavities 22 and slots in :ne plate, through which the securinfT screws 2l (i ,l passj the screws being 'tightened after the desired forward or rearward adjustment of the plate 2O has been completed and before the bearing plate QA and casing 1 have been attachedthereto. lt will of course be understood hat the cover should be in place upon the casing before the bar 3 is inserted therein since the'bar 9 passes through the depending loop and over the depending hoolr 311 of the cov-er in l order to loclr the cover in place on the casing.

1n order to obtain access to the interior of the casing it is of course necessary to hrst Withdraw the bar 3 from the casing in order to release the cover. The loclris non7 ready for operation and when the device is to be set to permit of a steering operation of the vehicle? the rotary cam 52 should be first shifted by the lrey to the position indicated in Fig, t ln this position of the operating cam the paivl 42 is in engagement with the bar 37 and holds the locking bolt 39 in its upward ror unlocled posiiion Within the casing. The hoolr Il@ is also disengaged from the notch 47 of the bar and when the cross rod is shifted relatively to the axle in the normal operation of the vehicle1 the bar 3 can reciprocate in and out of the casing and the casing can rotate upon the axle. lhen one desires to loclr the steering mechanism of the vehicle it is only necessary to insert the lrey within the cylinder lool: and rotate notch 4:( prevent removal of the "bar 3 from the casing to an extent Which could release the coverV The steering mechanism does not have to bef placed in any particular position in order te lock itj because as soon as the key is operated to release the pawl :or lever the bar 3 will be loclred against removal from the casing and the locking bolt Will be released, 1f an attempt is now made to move the vehicle over an y considerable distance3 some manipulation of the steering mechanism is necessary, and hence as the casi lated by the cross steering rod,

icclring bolt will be brought into alignnt with the locking` cavity l() and shifted into locking engagement therewith by the action of the spring 4:1. The cavity 40 is placed in the plate 2li in such a position that the steering mechanism Will be locked slightly to one side of a straight forward running position. Thus the vehicle can be moved for a short distance, such as 150 to 200' feet for example, if the necessity arose. it vehicle could therefore be removed from in fr of fire hydrant or burning building distance which would be necessary in case of an attempted theft or unauthorized use.I

The attaching parts are so assembled thaty accan only be had for removal 'or disablement of the lock, wh en in an unlocked condition. The material employed in vthev construction is a metal which can be hardened, preferably case hardened so 'as to render destruction or disabling of the parts by a thief extremely difficult and to entail a considerable delay. linasmuch as the removal of the key Will. lock the operating cam in either of its operative positions with respect to the loclzing lever or pawl l2 there is no danger of the jannning of the cam out of engagement with the parvl or lever and consequent locking of the steering mechanism Without Warning While the vehicle isV being operated. Case hardened spacers may be employed between the plate 20 and the ends of the arms of the U shaped clamping element 18 Whenever they are necessary in order to apply the lock to axles considerably greater in height than those of the ordinary vehicle. I have illustrated the locking device as applied to the cross rod and axle With the locking bar 3 upon the upper side thereof, but it is to be understood that if the apron under the hood interferes with this position of the lock, the loclr can be placed upon the cross rod and axle With the bar 3 underneath the same. 1t is obvious that various changes of the bar, and

in the details of construction herein described and illustrated may be made within the principle and scope ot my invention.
